E.G.
We engaged a business relationship and we needed to sign a contract. I gave the contract to you let you and your lawyer to have a review. I told you, please initial each page and sign the contract and return the contract back to me. You and your lawyer were Okay with the contract. You initialed and signed the contract and returned it to me. I took out a few very important pages from the contract, and initialed the other pages and signed the last page, made a copy and gave you back the copy.
Now some conflicts arose and you found out that your support information was in that pages were removed by me. You came to argue with me, and I said, sorry, that's your 致命缺陷, those pages only had your initials, not both sides' initials. You either lose your deposit or you buy whatever I as selling you, as is (I can provide you some discount, but please keep your mouth shut about those removed pages
)
